Solenoid spools.

Now that the test solenoids worked well it is time to get stuck in making the rest. Starting off with the spools.

Here is the design.

Turning on the lathe. I had to use a the tail stock and turn between centres as the nylon was deflecting. I think a more machining friendly plastic could have helped. I had more deflection problems with the drill producing a well undersized hole and ended up using a 6.5mm drill.

All finished.
